Device external pressure tubing, it is described to put on the mounting framework for being welded with and being installed and connected on vehicle body.
To make above-mentioned technical proposal more detailed and specific, the present invention also provides optimization technique side further below
Case, to obtain satisfied practical function：
The vibration absorber includes inner core, outer tube and arranged on rubber spring therebetween, the inner core, rubber spring and
Outer tube vulcanization connection.
The vibration absorber is columnar structured, and the casting trailing arm press fitting is plugged in the interior in-core.
The mounting framework includes mounting framework I and mounting framework II.
The mounting framework II is symmetrically arranged in described sleeve pipe both sides, the mounting framework I by symmetry axis of casing axis
Below casing one end.
Mounting hole is equipped with the mounting framework I and mounting framework II, is snap-fit attachment to by bolt on the vehicle body.
II both sides of mounting framework are equipped with the reinforcing rib of bending.
The vibration absorber other end opposite with the casting trailing arm insertion end is equipped with limiting plate.
The limiting plate is connected to bending plate on two mounting frameworks II for both ends, described in middle connecting plate interval
End face one end distance of vibration absorber.
The utility model engine suspension soft pad assembly compared with prior art, has the following advantages：The suspending soft cushion assembly, bag
The casting trailing arm of connection engine is included, vibration absorber, mounting framework, belongs to automobile suspended cushion technical field.Pass through rubber master
Spring vulcanizes inner core and outer tube, and casting trailing arm and casing are fitted in vibration absorber, are connected as one, reaches fixed installation engine
The purpose of vibration damping is realized at the same time, and it is easy to installation and maintenance.
Brief description of the drawings
The content expressed by the attached drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is schematic structural view of the invention；
Fig. 2 is internal structure sectional view of the present invention.
In figure mark for：1st, casting trailing arm, 2, casing, 3, outer tube, 4, rubber spring, 5, inner core, 6, limiting plate, 7, installation
Skeleton I, 8, mounting framework II.
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Inventive engine suspending soft cushion assembly, to improve vehicle NVH performances and ride comfort.As described in Fig. 1,2,
The engine suspension soft pad assembly is equipped with vibration absorber, and one end of casting trailing arm 1 is connected on engine, other end connection vibration damping
Device, vibration absorber external pressure tubing 3, is welded with mounting framework on casing 3, is installed engine and vehicle body by mounting framework
In the present invention, vibration absorber includes inner core 5, outer tube 2 and arranged on rubber spring 4 therebetween, inner core 5, rubber
Main spring 4 and outer tube 2 vulcanization connection.Vibration absorber is columnar structured, and the press fitting of casting trailing arm 1 is plugged in inner core 5.By in rubber
Main 4 part of the spring increase inner core 5 of glue and outer tube 2, casting trailing arm 1 and casing 3 are fitted in inside and outside vibration absorber respectively, by metal plate
Part mounting framework is welded on above casing 3, and vehicle body is connected to by mounting framework.This suspending soft cushion assembly by mounting framework, casting
Part trailing arm and vibration absorber are combined together, and reach support engine, reduce the purpose of in-car vibration.
The mounting framework of inventive engine suspending soft cushion assembly includes mounting framework I 7 and mounting framework II 8.Bone is installed
Frame II 8 is symmetrically arranged in 3 both sides of casing by symmetry axis of 3 axis of casing, and mounting framework I 7 is arranged on below 3 one end of casing.The branch
Arrangement stable structure is supportted, and three-way rigidity is easy to debug, technique is easily achieved.On mounting framework I 7 and mounting framework II 8
Mounting hole is equipped with, is snap-fit attachment to by bolt on vehicle body.II 8 both sides of mounting framework are equipped with the reinforcing rib of bending, improve branch
Support structure intensity.
Limiting plate 6 is equipped with the vibration absorber other end opposite with 1 insertion end of casting trailing arm.Limiting plate 6 connects for both ends
Bending plate on two mounting frameworks II 8, end face one end distance of middle connecting plate interval vibration absorber.It is real by limiting plate
Existing stroke limit, the vibration amplitude above and below engine can also be controlled in the stroke distances of setting, can effectively avoid sending out
Motivation collides with miscellaneous part because vertical vibration amplitude is excessive and produces noise, at the same also effectively avoid engine because
Damaged for shock.
Casting trailing arm 1 connects the mounting hole that engine end is equipped with perforation upper and lower surface, by bolt or screw to engine
It is located by connecting, mounting hole is equipped with three to be triangularly arranged, ensures stable connection.
Inventive engine suspending soft cushion assembly, include connection engine casting trailing arm 1, vibration absorber, mounting framework,
Belong to automobile suspended cushion technical field.Inner core 5 and outer tube 3 are vulcanized by rubber spring 4, casting trailing arm 1 and casing 3 are pressed
In vibration absorber, it is connected as one, achievees the purpose that engine is fixedly mounted realizes vibration damping at the same time, and it is easy to installation and maintenance.
The present invention is exemplarily described above in conjunction with attached drawing, but the present invention is not limited to aforesaid way, only
Want the improvement of the various unsubstantialities of methodology and technical solution progress using the present invention or directly apply to other occasions
, all fall within protection scope of the present invention.
